Light quark fragmentations into pions
- 24 Downloads
We discuss a process of hadronization of light quarks into charged pions in e + e − annihilations and in deep inelastic scatering of charged leptons and neutrino off nucleons. The corresponding semi-inclusive cross-sections of pions production we write in terms of quark fragmentation functions and fracture functions. We suggest a new method of measurements of fragmentation and fracture functions based on analysis of semiinclusive data.
